Description
本発明は、前記移動レンズ群移動量算出手段に替えて、前記ズームカム筒の回転角度を検出する角度検出手段と、前記ズームカム筒の回転角度と前記ウェイトの移動すべき位置との関係を記憶する記憶手段と、を備え、前記ウェイト駆動手段は、前記角度検出手段により検出されたズームカム筒の回転角度に基づいて前記記憶手段から対応する前記ウェイトの移動すべき位置を読み出し、読み出した位置に前記ウェイトを移動させる形態とすることができる。 In the present invention, instead of the moving lens group movement amount calculating means, an angle detecting means for detecting a rotation angle of the zoom cam cylinder, and a relationship between the rotation angle of the zoom cam cylinder and the position to which the weight should move is stored. Storage means, and the weight drive means reads the position to which the corresponding weight should move from the storage means based on the rotation angle of the zoom cam cylinder detected by the angle detection means, and reads the position to the read position. The weight can be moved.
